APPARATUS FOB TEMPERING CREAM AND OTHER LIQUIDS.

To all' whom 'it may concern.'

Beit'known that I, DARIUs W. PAYNE, a, citizen of the United States,residing at Minneapolis, .in the county of Hennepin and Statev ofMinnesota, have` invented certain new and useful Improvements inApparatus for Tempering Cream and other Liquids; and I do hereby declarethe following to'be a full,

. clear, and exact description of the invention,

suchvas will enable others skilled in the art to which it appertains tomake and use the same.

My present invention has for its especial object to provide an improvedapparatus for asteurizin or ysterilizing cream, milk and 'quids of l1 edescription, but is capable of many other uses and broadly considered isa device for tempering liquids.

The invention consists of the novel de- `vices and combinations ofdevices hereinafter described and defined in the claims.

` 'In the accom an drawin swhich illus- P )rmi g tratethe invention, lie characters indicate. like parts throughout the several views.

Referring to the drawings, Figure l'is a view partly in elevation butprinci ally in vertical section on the line m1 o Fig. 2, showing thetempering ap aratus. Fig. 2 is an end elevation of the sai apparatus.Fig. 3 is a transverse vertical section taken on the line x3 ac3 ofFig. 1. Fig. 4 is aview partly in elevation, but rinci-pally in.vertical secu l)ar line x* x4 of Fig. 5, illustratinga slight y modifiedform of the tempering a paratus. Fig. 5 is a left end eleva- Fig. 6` isa transverse vertical section taken on the line az of Fig.- 4.

Considering first the specific form of apparatus illustrated in- Figs. 1to 3 inclusive, the

the chamber within the inner drum 4v through a sup ly pi e 9, and it isadapted to be drawn off rom t e bottom of said chamber through a valvecasing 10 and discharge pipe 11. The passage through the casing 10 1snormally closed by-a valve 1 2`. An `upwardly extended tangentialdischarhgefneck 13 opens from the interior of the inner drum 4,preferably near the right hand end thereof.

Under certain conditions hereinafter noted, this discharge neck 13should be closed by a ca 14. f

Extending through and journaled in. the left hand bearing sleeve or hub3 isa tubular shaft 15; and extending through the right' handV bearingsleeve or hub 3 .is a rotary pipe or tube 16. Rigidly secured totheinnerend of the tubular shafts 15 and 16 arediametrically extended headbrackets 17.' These two.

heads 17 carrya pair of hollow paddleblades 1S preferably constructed ofthin sheet metal formed quite. flat and thin in cross section andlocated in the same plane with each other on the opposite sides of theaxis of therotary reel made up of the said partsv 17 and 18. Spacingpipes 19 are preferably placed within the hollow blades 18 and areseated at their ends in the heads 17, thereby rigidly connecting thesaid heads and stiffening the said hollow blades. The heads 17 lareformed with hollow hub portions 2O that are connected by a pipe or tube21, the right handkend 'of whic is preferably plugged or closed." Thehollow hubs 2() are provided with ports 20a that communicate throughports 20h Withzthe interiors of the hollow blades 18. '.The tubularshaft 15 opens directly into the left hand-port 20, while the right handtubular shaft116 opens directly from the right hand port 20".

Journaledon the tubular shaft lbut held against sliding movementsthereon,-are preferably two driving-'pulleys 2.2 ,and 2,3 that areprovided with half clutches 2,4 an'dl25 on their opposing hub portions.

The numeral 26 indicates a clutch member that is mounted to slide on butcaused to rotate with'the tubular shaft 15, and is pro- 'valve 38.

, posed in the pipe 30 below vided at its opposite faces with teetharranged to engage with the said half clutches 24 and 25. Said clutchmember 26 is moved by a shipper lever 27, shown as pivoted to an arm 28on the left hand pedestal bracket 2,

Power driven belts, (not shown) will run over the two loose pulleys 22and 23, As is evident, when the small pulley 23 is coupled to the hollowshaft 15 by the clutch member 26, the reel'made up of the heads 17 andhollow blades 18 will ybe rotated at a much higher speed than when the.said large pulley 22 is cou led to said shaft 15;

The water circulating connections to the apparatus are 'as follows: Awater supply pipe 29 leads from a suitable source of water supply, suchas an elevated water tank, and extends to a depending pipe 30.' The pipe30 leads into the lower portion of the water chamber formed between thetwo drums 1 and 4, `and vat its intermediate portion it is provided witha T 31 in which the outer end of the tubular shaft 15 is shown as journaled. The supply pipe 29 is preferably provided with a valve 32. Atthe other end of the machine, to-wit, as shown in Fig. 1, at the righthand end thereof, is an upright pipe 33 that is open at its upper end. Abranch pipe 34 connects the upper right hand portion of the waterchamber 5 with the upper portion of the pipe At its intermediateportion, said pipe 3\3\is provided with a T 35 in which the outer end ofthe tubular shaft 16 is journaled. A horizontal water return pipe 36 isconnected to the lower end of the pipe 33 by a T-coupling 37 in which isa three-way The T-coupling 39 in which is a three-way valve 40 isinterposed in the pipe 34. The forward end of the pipe 36 is 'connectedby an elbow 41 to an upright return pipe 42. AT-coupling 43 connects theends of the pipes 29, 30 and 42. In this coupling 43 is a three-wayvalve 44. v

The numeral 45 indicates a valve interthe coupling- 31.

rlhe numeral 46 indicates a drain cock which opens from the lowerportion of the water chamber 5 through the bottom of the outer drum 1. A

Steam is supplied for the purpose of heating the water and for producinga `forced circulation thereof through the water pipes and otherconnections described and including, of course, the -water lchamber 5.As shown, the steam is supplied from the pipe 47 that leads from asuitable source. of steam supply (not shown), is provided with a valve48 and terminates in the contracted nozzle 49, which nozzle, as shown,extends through and ter minates in the elbow coupling 41 and stands insuch position that steam discharged therefrom will not only heat thewater in the pipe 42 but will force the same upward. Of course, ifdesired, the said steam pipe 47 might be provided with several dischargenozzles located at different points within the water circulating pipes.i Operation. When the apparatus is to be used as Aa pasteurizer,sterilizer, or morel generally stated, for the purpose of heating Aaliquid contained withinthe inner drum 4.

the three-way valves 44 g 40 and 38 should' be set in the .osition shownin Figs. 1 and 2; The water w ich is heated and set in motion withinthepipe 42, by the discharge of steam from the nozzle 49 will be forceddownward through the pipe 30 and will pass in part into the waterchamber 5 and in part through the hollow shaft 15, into the port 20i ofthe left hand reel bracket or head 17. From the said port 2()a the waterasses through the ports 20binto the hollow filades 18, and from thencethrough the ports 201. and 20a of the'. right hand reel bracket or head17 and from thence through the hollow shaft 16 into the 85 vertical pipe33. The waterintroduced into the left hand end of the water chamber 5.passes through said chamber and around the lnner drum 4, and fromthence through the branch pipe 34into the vertical returnpipe 33.l 90

From the pipe 33, the water is returned by the pipe 3 6 to the lower endof the vertical pipe 42, where it is again subjected to steam from thenozzle 49 and is thereby again reheated andv given further movement linthe direction already indicated. It willthus be seen -that the cream orother liquid contained within the drum 4 will be heated not only fromcontact with the hot surface of the said drum 4, but also by contactwith the hotsurfaces of the hollow blades and heads of the rotatingreel. This reel also thoroughly stirs the cream or other liquid beingtempered, and thereby insures perfectly even tempering or heatingthereof.

For many purposes, and. especially where complete pasteurization orsterilization is required, such as when sterilizing cream in theripening process, it will usually be de-A sirable to confine the body ofcream within the inner drum 4. When this is the desired action, the cap14 is placed on the discharge neck 13, the valve l12 isv closed, and thereel is then preferably rotated at a slow speed. F or many otherpurposes, however, it will be found desirable to continuously circulatethe cream or other liquidV being heated through the chamber within theinner drum 4. When this is the desired action, the ca should be removed`from the discharge nec 120 13, the reel should be rotated at its 'hi hspeed, and the valve 12 should, of course, lgie kept closed, Then thereel is'ithus rotated at a high speed, centrifugal force will spread thecream out in a thin layer against the inner surface of the drum 4 andwill discharge .cream or other liquid from the drum 4 through thedischarge neck'13, from which neck it may be' conveyed by a hose orsuitable tube,

not shown, to some suitable re- 'ceptacle therefor. When the apparatusis to be'used as a coo apparatus, the steam should, of course, be s utofi, `and cool Water should be allowed to ru'n through the Waterconveying connections described. In this instance, however, thethree-Way valve 44 should be given-a one-fourth' rotation in a directionreverse to the movements of the hands of a watch, so as to cut off thepipe 42 While open' the pipe 29 to pipe v30. 'The three-way va ve 40should be given a -onehalf rotation, so as to open the depending arm ofthe T-coup 39 to exhaust. The three-way valve 38 s ould be given aonefourth rotation in a direction reverse to that of the movements ofthe hands of a watch, so as to open the depending arm of the T -couplin37 to exhaust. With the said valves 38 an 40 moved as 'ust noted, thewater, after passing through t e chamber 5 and the connections.including the reel, and after 4having been warmed or heated, will beexhausted or run off from the couplings 37 and 39.

.The construction illustrated in Figs. 4, 5 and 6 is the same as thatalread described, with the followin exceptions: he tangential dischargenec '13, 1n. this arrangement, is located at and extends upward from thecentral portion, of the drum 4, and is provided with a displaceable ca14. An inletv tube 9 for the cream or ot er liquid to be tempered opensinto each end ofthe drum 4. This arrangement is especially adapted forlarge machine'swhere very high capacity is required and where it isdesirable to have a continuous flow of cream or other liquid through theinner drum or tempering chamber. Also in this modified construction, theleft hand reel head or bracket 17 is shown as provided with a long port20 that opens directly into the ends of the head spacin pipes 19, andthe said pipes are provide with lateral perforations 19 that open di.-rectly into the chambersof the hollow reel blades 18. Also as shown, thesteam supply pipe 47 is provided with branch pipes 47a that open intolthe water ,compartment 5 between the two drums 1 and 4 and terminate inperforated nozzle sections 47 d. Asis evident, steam discharged fromthey nozzle pipes 47d, will very rapidly heat the water contained in thecom artment 5.

In the apparatus s own in 4, 5 and 6, the cream is fed into both ends ofthe tempering chamber and under the action of the rotary reel is spreadout overt'he inner surface of the cylindrical portion orfjsaid temperingchamber and forced to and out of the centrally located. discharge neckor passage as fast as it isfed into said tempering chamber throu h thetwo inlet passages.
